Open source finite element code that deal with contact....
I am looking for any open source finite element codes that may be out there that deal with contact mechanics.
Two Post-doctoral researcher positions available
TWO post-doctoral researcher positions are available immediately at Academia Sinica in Taipei, Taiwan.
We are looking for candidates who are interested in the following projects
1) Molecular simulations of hydrophobic surface
2) Molecular simulations of novel power-storage materials
Candidates must have experiences in molecular simulations or ab initio calculations. For experienced candidates, the annual salary could be over $30,000 USD.
Calculating the activity coefficient of aluminium in the solid state as well as in the liquid state.
I am trying to calculate the activity of aluminium in the liquid state or solid state. The bottom line is that I want to know if Aluminium during oxidation is more active in the liquid state than in solid state.If so, how can I prove it.
Viscoelastic RVE for CNT Composites
Hi
all,
I am Mohammad Aramfard senior student of mechanical engineering and I joined this
great forum yesterday, so I am not very familiar with regulations and rules.
I am working on modeling CNT composites using cylindrical RVE and I found up to
now that there isn`t a viscoelastic RVE for representing behavior of these
composites.
I want to know is there any works done in this field?
And also I have another question, Is there any exact
solution for elastic cylindrical RVEs?
Thank you all,
Help in ABAQUS
Dear all,
In my FE model (pin on disc), I would like to define a contact property between pin and disc with a friction defination available in ABAQUS. I have assumed that friction coefficient depends on parameters like slip rate, pressure and temperature only. When i used friction coefficients with slip rate and pressure, model works without any error but if i use friction coefficients with slip rate, pressure and temperature, the model doesn't work and come up with following errors;
smeared crack concrete output problem
Hello Guys.. I am modelling single dry shear key which is in the joint of segmental bridge, I model the concrete by using
smeared concrete model.the model in working and i get the results .Please can anyone help me how to find the crack
pattern ?? Really i stoprd at this point for more than 15 days !! I read the manual and it says that output information for
smeared concrete model is CRACK and CONF but I cant figure out where can I find it ..on the other word how I can
Microscale characterization of granular deformation near a crack tip
Abstract
This paper presents a study of microscale plastic deformation at the crack
tip and the effect of microstructure feature on
the local deformation of aluminum specimen during fracture
test. Three-point bending test of aluminum specimen was conducted
inside a scanning electron microscopy (SEM) imaging system.
The crack tip deformation was measured in situ utilizing SEM imaging
capabilities and the digital image correlation (DIC)
full-field deformation measurement technique. The microstructure feature
at the crack tip was examined to understand its effect on
the local deformation fields. Microscale pattern that was suitable
